Part of the problem is the balancing act between a real spec class and keeping costs down.

The point of a spec class from a racer's point of view is to showcase talent, however that is not what the OEMs want out of it and they want to sell new bikes.

I am waiting to see how things shake out in the rules for the WERA National series before making my opinion on how successful the class could be. It could be extremely successful if used/older bikes could be run and/or a way to limit the initial investment is made. But, if they make it 2006/7 or newer I don't expect to see very full grids in the first year which will simply fuel the critics who say "no one wants to race small displacement equally matched bikes".
